Diagnosis
Diagnosis. Body size: 614–647 × 381–415. Rostrum rounded. Lamellar setae inserted close to each other.

No distinct differences in size between females and males. Integument (Figs 1, 3). Body color light brownish. Body surface, subcapitular mentum and genae, genital and anal plates, and legs punctate. Centro-dorsal part of prodorsum with sparse cerotegumental tubercles (diameter of tubercles up to 12), lateral parts of body with small, dense cerotegumental tubercles (diameter of tubercles up to 4). Prodorsum (Figs 1, 3). Rostrum slightly protruding, rounded. Rostral (ro, 94–106), lamellar (le, 90–98), interlamellar (in, 110–114) and exobothridial (ex, 57–65) setae setiform, barbed; in thickest, ex thinnest, le located close to each other, divergent medio-distally. Bothridial setae (bs, 57–61) fusiform, indistinctly pointed distally, barbed, stalks slightly shorter than heads. Longitudinal rows of muscle sigillae poorly visible anteriad to bothridia. Interbothridial muscle sigillae distinct. Lateral ridges (rl) well developed, clearly not reaching acetabula IV. Notogaster (Figs 1, 3). Twelve pairs of notogastral setae, h1 absent. Setae da, la, dm, lm, dp, lp and h3 long (147–155), setiform, thickened, barbed, h2 (73–77) and p1 (65–69) thinner, stiff, barbed, c, p2 and p3 shortest (36– 41), thinnest, smooth. Lyrifissures ia, im and ips well developed, ih and ip not visible. Opisthonotal gland openings (gla) located laterally and removed from im. Gnathosoma (Figs 4–6). Subcapitulum longer than wide: 131–139 × 106–110. Three pairs of subcapitular setae and two pairs of adoral setae setiform, barbed, h (61–69) longer than m (45–53), a (20–24) and or1, or2 (16– 20). Length of palps: 102–106. Postpalpal setae (6) spiniform. Length of chelicerae: 131–139. Cheliceral setae setiform, cha (36–41) straight, with long cilia unilaterally, chb (26) slightly curved in median parts, barbed. Trägårdh’s organ (Tg) tapered, indistinctly granulate. Lateral podosomal and epimeral regions (Figs 2, 3). Epimeral setae setiform barbed, 3 c and 4 c (98–102) longer than 1 b, 4 a (65–73), 1 a, 3 b, 4 b (49–53), 1 c, 2 a and 3 a (32–41). Discidia rounded distally. Anogenital region (Figs 2, 3). Five pairs of genital (g1 – g5, 28–32), one pair of aggenital (ag, 53–61), three pairs of adanal (ad1 – ad3, 53–57) and two pairs of anal (an1, an2, 41–45) setae setiform, barbed. Setae ad1 slightly thicker than ad2 and ad3. Adanal lyrifissures (iad) distinct. Legs (Figs 7–10). Claws slightly serrate on dorsal sides. Formulas of leg setation and solenidia: I (1–5 – 2–4 – 20) [1–2 – 2], II (1–5 – 2–4 – 16) [1 – 1–2], III (2–3 – 1–3 – 15) [1 – 1 –0], IV (1–2 – 2–3 – 12) [0–1 –0]; homology of setae and solenidia indicated in Table 1. Setae p setiform on tarsi I, and very short, conical on tarsi II–IV.

Materials Examined
Material examined.Holotype (male) and 11paratypes (9 males and 2 females): Peru, 09° 37 'S, 74 ° 56 'W, Huánuco Department, Puerto Inca Province, Yuyapichis District, Área de Conservación Privada, Panguana (biological field station), nearby Rio Yuyapichis (river), 230–260 m a.s.l., upper soil and leaf litter in the primary evergreen lowland rainforest, Winkler extraction, 20.IX. 2013 – 07.X. 2013 (S. Friedrich and F. Wachtel). Type deposition. The holotype is deposited in the collection of the Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Lima, Peru; 11paratypes are deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia.
Etymology
Etymology. The specific name is dedicated to my friend and colleague, zoologist, Dr. Stefan Friedrich (Zoologische Staatssammlung München, München, Germany) for his help by handling the great diversity of the collected Peruvian mites.
Discussion
Remarks.Aeroppia friedrichi sp. nov. is morphologically most similar to Aeroppia nasalis Mahunka, 1984 from the Neotropical region (see Mahunka, 1984) in having well-developed prodorsal setae, long dorsal notogastral setae, and in location of lamellar setae (close to each other). However, the new species differs from the latter by the absence of striate ornamentation on the notogaster (vs. present) and notogastral setae h1 (vs. present), and the presence of setiform adanal setae ad1 (vs. dilated in median parts). Also, the new species is morphologically similar to Aeroppia sp 4. from the Neotropical region (see Hammer 1962; Subías et al. 2004),but, differs by the smaller body length (614–647vs. 920), thickness of notogastral setae p1 (not thicker than dorsal notogastral setae vs. thicker) and short notogastral setae p2 and p3 (vs. of medium size).
